Special alloys are unique metal mixtures designed to enhance specific properties, such as strength, corrosion resistance, or heat tolerance. These alloys often combine elements like nickel, copper, or titanium with base metals like iron or aluminum to achieve desired characteristics for various applications. Industries such as aerospace, automotive, and electronics frequently use special alloys to improve performance and durability. For example, stainless steel is a well-known special alloy that resists rust and staining, making it ideal for kitchenware and medical instruments. Other examples include superalloys, which are used in jet engines for their ability to withstand extreme temperatures.
